Under the background of environmental protection, the development trend of water-based epoxy resin industry continues to improve

Water-based epoxy resin refers to a water dispersion, emulsion or aqueous solution formed by dispersing epoxy resin in the form of particles, droplets or colloids in an aqueous phase. Water-based epoxy resin has the advantages of convenient transportation, easy cleaning, environmental protection, heat resistance, corrosion resistance, etc., and is widely used in the fields of industry, electrical appliances and medical equipment. According to the different charges carried by the central ions, water-based epoxy resins can be divided into cationic resins and anionic resins.

According to the “2022-2027 China Waterborne Epoxy Resin Industry Application Market Demand and Development Opportunities Research Report released by the Industrial Research Center , under the background of environmental protection, the market demand for water-based epoxy resin is increasingly strong. The global water-based epoxy resin market size will reach 1.23 billion yuan in 2021, a year-on-year increase of 11.8%. my country is one of the fastest growing water-based epoxy resin markets in the world. In 2021, the market size of my country’s water-based epoxy resin market will reach 40 million yuan, a year-on-year increase of 7.6%.

Epoxy resin water-based methods include curing agent emulsification method, self-emulsification method, direct emulsification method and phase inversion method. The curing agent emulsification method can be used to prepare water-based epoxy resin emulsion, which has the advantages of convenient operation, but the product shelf life is short; the self-emulsification method is used to prepare cationic, anionic and non-ionic water-based epoxy resins, and the storage stability of this method is Better; the amount of emulsifier used in the direct emulsification method is lower, but the film-forming property of the product is poor; the phase inversion method is one of the easiest methods to realize the industrial production of water-based epoxy resin.

Water-based epoxy resin has a wide range of applications, and water-based epoxy coatings have the largest demand. Water-based epoxy coatings are in high demand in rail transit, ships, containers and other fields, and are often used as anti-corrosion coatings. Containers are special tools for international logistics and transportation, and their raw materials are metal materials. During the transportation process, due to weather changes, seawater impact, ultraviolet radiation, etc., the corrosion problem of the container cannot be avoided. Water-based epoxy coatings have excellent performance and can meet the performance requirements of containers for anti-corrosion coatings, and their application prospects are broad.

Water-based epoxy resin has environmental protection advantages. In recent years, with the increasing awareness of green environmental protection, competition in the water-based epoxy resin market has become increasingly fierce. In the global market, Dow Chemical of the United States, Hexion of the United States, Sigma-Aldrich of the United States, and KUKDO of South Korea are the world’s leading water-based epoxy resin companies, occupying a major share of the market. In the local market, Jinan Shengquan Group, Guangdong Sainty New Materials, Foshan Gaoming Tongde Chemical, etc. are the main manufacturers of water-based epoxy resin in my country.

Industry analysts said that my country’s water-based epoxy resin industry is developing rapidly, and with continuous breakthroughs in technology, its output will continue to increase. Water-based epoxy resin has excellent performance and is widely used in many fields. Benefiting from the gradual release of market demand and strong support from national environmental protection policies, the water-based epoxy resin industry will have broad development prospects in the future.
